BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to a composition comprising an extract of Actinidia arguta having preventing and treating activity of baldness disorder and seborrheic skin disease.

2. Background Art

The present invention relates to a composition comprising hardy kiwifruit extract having preventing and treating activity of baldness disease and seborrheic skin disease, and especially, a composition comprising the crude extract, non-polar solvent soluble extract, or purified fraction of kiwifruit extract for the prevention and treatment of baldness disease and seborrheic skin disease.

Baldness syndrome is frequently occurred in middle-aged male and classified into two types of baldness. One is male pattern baldness alternatively named as an alopecia seniles or androgenic alopecia generally occurred in the forehead or calvaria of middle-aged male, and another is alopecia greata which shows relatively concrete border line of alopecia and frequently being occurred in juvenile person. The syndrome is mainly occurred in male and even in female (M. Inaba et al; Androgenetic alopecia, Springer-Berlag, Tokyo, Japan, 1996).

There has been reported that alopecia is originated from genetic factor, the progress of aging, drug abuse, radioactive treatment and the stress occurred after serious illness etc. It has been known that main factors of alopecia are over-production of androgenic hormone, blood circulation problem in scalp and vitamin deficiency essential to hair metabolism in biochemical and physiological aspects and the main factor of male pattern baldness relates to androgen and steroid hormone, in particular, 5-α-reductase converting testosterone to 5-α-dihydrotestosterone (DHT) and being distributed in sebaceous gland, keratinocytes of hair follicle, dermal papilla cell, sweat gland, root sheath of the scalp hair follicle etc and aromatase converting androgen to female hormone such as estradiol. The etiological origin of alopecia greata is known to be the disorder of autoimmune system, especially the lymphocyte CD4+ disorder in melanocyte, keratinocyte, dermal papilla and vascular endothelium (J. Shapiro et al; Therapeutic agents, Dermatol. Clin., 16 (2) pp 341-356, 1998).

Various conventional drugs for the treatment of alopecia have been developed and used till now. For example, finasteride, an oral 5-α-reductase inhibitor, has been available in the market, however it has several disadvantages such as repetitive recurrence in case of the cease of administration, limit to the use in pregnant women, and sexual dysfunction due to long-term administration; minoxidil, one of available drug in the market, has been used to treat male pattern baldness together with other agents for example, cell division accelerator, vasodilator, capillary formation promotor, immuno-suppressor, cAMP modulator, EGF (epithelial cell growth factor) and cell proliferation modulator, however it has also adverse effect such as repetitive recurrence and rapid blood pressure lowering effect in case of the cease of administration too; ACTH (adrenocorticotrophin) as a representative immuno-modulating agent acting on limphocyte to suppress hyperactive immune system has been administrated to treat alopecia greata by a form of ointment or injection, however it has also several disadvantage such as recurrence or adverse effect, which cause to difficulty in long term administration. Besides above described drugs, cyproterone actate, spironolactone, estrogen and so on have been reported to treat alopecia (J. Shapiro et al, Hair regrowth, Therapeutic agents, Dermatol. Clin. 16 (2), pp 341-356, 1998).

As described above, most of conventional drugs do not provide with enough efficacy to accomplish satisfactory activity and have several advantages such as a recurrence or adverse effect, therefore there have been lots of approach to obtain new drug which provides with satisfactory effect and reduced adverse effect till now.

Meanwhile, there has been lots of concentrated effort to investigate effective drug from natural resource to treat and prevent alopecia disease till now.

As an alternative approach, there have been several reports on the composition comprising an extract of crude drug having hair growth stimulating effect, for example, plant extract belonged to Orchidaceae disclosed in Korea Patent Registration No. 015667, vitex seed and bear fat in Korea Patent Registration No. 0161338, an extract of Rhododendron fauriae in Korea Patent Publication No. 91-106, pine leaf extract in Korea Patent Publication No. 96-40346, an extract of crude drug consisting of torilla seed, pine leaf and silkworm moth in Korea Patent Publication No. 90-2757, an extract of crude drug consisting of Acanthopanax sessiliflorus, Astragalus membranceus, Polygonum multiflorum, Dioscorea nipponica and Fagopyrum esculentum in Korea Patent Publication No. 2000-24499, an extract of crude drug consisting of Pinellia ternata, Eugenia Caryophyllata, Rubus coreanus, Zanthoxylum piperatum, Vitex rotundifolia, Salvia miltiorrhiza, and Thujae semen in Korea Patent Registration No. 259037, the fat obtained by heating silkworm and their byproduct, at 200° C. for 15 mins, an extract of crude drug consisting of Panax ginseng, Angelica sinensis, Astragalus membranceus, Polygonum multiflorum, Juglans sinensis, Rubus coreanus, Rehmannia glustinosa, Psoralea corylifolia, Pinus densiflora, Vitex rotundifolia, Carthamus tinctorius and Ligustrum lucidum in Korea Patent Publication No. 90-13934, an extract of crude drug consisting of silkworm moth, silkworm eggs, silkworm pupa, black sesame seeds, sesame seeds, brown seaweed, and walnuts in Korea Patent Publication No. 90-5952, mixed powder of mung beans, soy bean, perilla seeds, sesame seeds, walnuts, layer, sea mussel, oyster, anchovy, brown seaweed, and yeast concentrates in Korea Patent Registration No. 260673, an extract of fruits, root, branch, leaf, flowers of Lycium chinensis, and corn silk in Korea Patent Publication No. 2000-36534 etc. However, the hair growing effect of above described composition disclosed therein have not been fully supported or identified in any of disclosure herein.

Actinidia arguta, A. polygama and A. kolomikta belonged to Actinidiaceae, are distributed in Siberia, the northern area of China, North and South Korea. More than 30 species belonged to Actinidiaceae have been reported. Among them, the fruit of Actinidia chinensis or A. delicious have been named as a kiwi and Actinidia arguta, and other identical genus fruit have been used as materials of Chinese medicine named as ‘mihudo’, to treat liver disease, gastrointestinal disease and urogenital lithiasis without toxicity (Chung B. S, and Shin M. K.; HyangyakDaesacheon, Youngrimsa., pp 386-388, 1998).

Meanwhile, there have been several applications regarding on the activity of Actinidia fruit to treat or prevent various medicinal diseases till now.

For example, Korea Patent Registration No. 344147 discloses health beverage containing an exudates of Actinidia fruit as a main component and the preparation thereof; Korea Patent Registration No. 134024 discloses health beverage containing an fruit extract of Actinidia chinensis or A. delicious as a main component and the preparation thereof; Korea Patent Publication No. 1996-37061 discloses a hepato-protective agent and anti-cancer agent comprising an extract of Actinidia fruit as a main component; Korea Patent Publication No. 2002-78467 discloses health beverage containing an extract of crude drugs consisting of Actinidia arguta, Hovenia dulcis, Lycium chinensis, Schizandra chinensis, Artemis capillaries, Pueraria thunbergiana, Glycyrrhiza uralensis, Lagenaria siceraria, Aralia elata, Polygala tenuifolia, Angelica sinensis, Atractylodes macrocephala, Gardenia jasminoides, Astragalus membranaceus, Carthamus tinctorius and Cordyceps militaris for the improvement of liver function.

However, there has been not reported or disclosed about treating or preventing activity of hardy kiwifruit extract on alopecia and seborrheic skin disease in any of above literatures.

To investigate the treating effect and preventing effect of heady kiwifruit extract on alopecia and seborrheic skin disease, the inventors of present invention have intensively carried out in vivo and in vitro experiment concerning the inhibition effect on the reproduction of DHT (dihydrotestosterone) together with clinical experiment concerning on the hair growth stimulation and seborrheic skin disease. As a result of the investigation, the inventors finally completed the present invention by confirming that the hardy kiwifruit extract reduced blood DHT level, and inhibited the falling out of hair and seborrheic skin disease.
